Mysql syntax error on stored procedure

Question

I run this code as a sql script from command line, and I get "you have an error in your SQL syntax" almost in all lines! Any ideas what is wrong here?

CREATE PROCEDURE updatemandate()
 BEGIN
   DECLARE _mandate_id BIGINT(20);
   DECLARE _has_succesful_payment tinyint(1);
   DECLARE done INT DEFAULT 0;
   DECLARE cnt INT;
   DECLARE mandateCursor CURSOR FOR Select mandate_id, has_succesful_payment From mandates;
   DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1; 
   OPEN mandateCursor;
   allmandates: LOOP
   Fetch mandateCursor INTO _mandate_id, _has_succesful_payment;
   IF done THEN LEAVE allmandates;
   END IF;
    Select COUNT(*) FROM payments WHERE mandate_id=_mandate_id AND status='OK' into cnt; 
            IF cnt>0 THEN
            SET _has_succesful_payment=1;
            END IF;

   END LOOP allmandates;
   CLOSE mandateCursor;
 END

Answer 1

The ; character is the default delimiter, so when MySQL sees the first ; it thinks you are done. When you create a sproc, you need to declare a different delimiter character, like so:

DELIMITER $$

CREATE PROCEDURE updatemandate()
READS SQL DATA
 BEGIN
   DECLARE _mandate_id BIGINT(20);
   DECLARE _has_succesful_payment tinyint(1);
   DECLARE done INT DEFAULT 0;
   DECLARE cnt INT;
   DECLARE mandateCursor CURSOR FOR Select mandate_id, has_succesful_payment From mandates;
   DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1; 
   OPEN mandateCursor;
   allmandates: LOOP
   Fetch mandateCursor INTO _mandate_id, _has_succesful_payment;
   IF done THEN LEAVE allmandates;
   END IF;
    Select COUNT(*) FROM payment WHERE mandate_id=_mandate_id AND status='OK' into cnt; 
            IF cnt>0 THEN
            SET _has_succesful_payment=1;
            END IF;

   END LOOP allmandates;
   CLOSE mandateCursor;
 END$$

DELIMITER ;

Also a good idea to add the READS SQL DATA to the sproc definition in case you need to support binary logging .

您是否尝试过将delimiter //放在CREATE语句之前，并用END //更改最后一行？
